Cassini

Cassini's infrared spectrometer detected molecules like acetylene around Jupiter's poles. Acetylene offers clues into the chemical reactions that take place when sunlight interacts with Jupiter's atmosphere.

These images made by NASA's composite infrared spectrometer show the distribution of the organic molecule acetylene at the north and south poles of Jupiter. It is the highest-resolution map of acetylene to date on Jupiter. The detection helps scientists understand the chemical interactions between sunlight and molecules in Jupiter's stratosphere.
